Lumens: 1,3,10,30,100,300 (some simple logarithmic progression, with a low at 1 or less, highest at least 100)
UI: Deep press - on/off… shallow press - mode switch … no memory… start on lowest… no strobe… no PWM…
Form factor: very short, preferably side switch
Cost: under $20
Misc: li-ion compatible, ability to use alkaline or carbon zinc to zero volts, Nimh should be protected under 1V, shock protected (potted), waterproof, some kind of clip
Don’t need: thermal protection, magnet, zoom, charger, tail stand
Something like the BLF-348 would be ideal, even though it has a tail switch - why can’t it just have 3 or 4 modes
Are there just not ‘drivers’ that can easily do this?
Is it the small size, small current capability?
Because most of the time people aren’t really interested in elaborate interfaces for their keyring light. KISS at work.
But if you need it, you can find/build a custom driver with desired modes and install it into your body of choice.
1,3,10,30,100,300 would be a horrible driver …none of the modes would look any different than the last one . it would be tiresome and painfully dumb .
Believe me the original Eastward YJ-Y09 which was concieved by Mr admin .suffered this fatal flaw . it has a 1 lumen and a 8 lumen …both of which look exactly the same and it forces you to click twice just to get past a dumb mode that doesn’t need to be there .
I understand the concept but emitters are getting much more efficient these days and a lumintop tool on med is plenty of light most of the time. 3-4 hours on medium means it’s a pretty good little light to EDC.
The AAA lumintop tool with a NIMH battery is
only 25 grams .
Ti tool –30g
SS BLF-348 –35g.
copper tool –45g.
……………………
while a AA
zebralight H501-50g
Eagletac d25A ti –50g
$2- AA zoomie-50g
x=tar wk50-55g
klarus M-i7 55g
U torch UT 01 –65g
3 times the power or capacity but also double the weight …
* All weights above include a AAA or AA battery
K.I.S.S, that’s why
because most daily use of aaa light is short-time using, so, runtime isn’t really matter, a little over brighter than you need doesnt kill runtime much
the only reason i need many mode flashlight is when i want to maximize the runtime( for example, a led consumes 1.5A maybe just 10% brighter to my eyes than a led consumes 1A , 10% is not that much, so i will use 1A mode)
if you could switch fast [like astrolux S1] then having a lot of levels is a good thing
it has 7, i can get through them all in under 2 sec
it even has ‘’go down one level’’ - which requires a long press - i never do that because i can go up 6 faster than i can go down 1
re 300 lumens - it is just an example, 10440 can do it
I carry a Factor Equipment Mizpah 130, but at just under $30, it’s not exactly budget.
It’s mode sequence is H-M-L-Strobe and has last mode memory - including strobe.
The modes are rare enough apart that there is obvious difference in brightness.
It’s got an optic and a large, floody hot spot with some spill.
It’s two-way clip is the best I’ve ever encountered - it will clip on thick brimmed hats securely and will always return to it’s original shape. The clip is the reason that I tolerate the L-M-H-S mode sequence.
